One of the things that isn’t really compiant with the idea of the abstract control model, are the values you see when you are editing an effect. The rate and scale are in percentage and the span is in degrees. I think this could be closer to real-life values. Like beats-per-minute/Hz (like with the strobe)/etc. for rate. Better would be a more graphic display in wich you could really see what you are doing. Things like span or offset would be clear at first sight, as now I break my head every time I use it.

Agreed that a snazzy graphic image of bugs going around on a curved line would show offset nicely.

FYI - a lot of timing values can be done in % or real time (seconds). You just have to change the first tweaker, then you can enter cycle time in seconds (or points of a second)

FYI2 - Span in degrees says how many degrees along the function each fixture is seperated by. Fan sets the position along the function of the last fixture in the FX and all other are spread out evenly. You always have the option of both. A fixture at 360 degrees along a function is at the same position as the one at 0 degrees.
